VA 550 - Flow meter for heavy duty industrial applications

Flow meter for heavy duty industrial applications

The immersion flow meter VA 550 is the ideal flow sensor for installation into existing compressed air resp. gas lines from 3/4“ up to DN 500.

4 values in the display: Nm³/h, Nm³, Nm/s, °C units freely adjustable
Min/max values and daily/hours/minutes average values freely adjustable
All measured values, settings like gas type, inner diameter, serial number and so on retrievable via Modbus RTU
Comprehensive diagnosis functions readable at the display or remote access via Modbus like e. g. exceeding of max/min values °C, calibration cycle, error codes, serial number, all parameters readable and adjustable
Notification in case of exceeding of the calibration cycle
Standard version accuracy 1.5 % of m.v. ± 0.3 % of f.s.
Precision version accuracy 1.0 % of m.v. ± 0.3 % of f.s. up to
40 calibration points with certificate
Measuring span of 1 : 1000 (0.1 up to 224 m/s)
Configuration and diagnosis via display, hand-held instrument
PI 500, PC service software on-site
Gas type (air, nitrogen, oxygen, argon and so on) freely adjustable
Reference conditions °C and mbar/hPa freely adjustable
Zero-point adjustment, leak flow volume suppression
Pressure loss negligible
Flow measurement in both directions via flow direction switch
